Can you write ANY JavaScript number using only these 3 symbols?

I've given myself a challenge to write any JavaScript number using only 3 symbols, plus, left square bracket, and right square bracket. Spoiler - it was a success!

His 1 key is broken... But he's incrementing 1... This is dedication.

bro extracting 'e' killed me. this content is insane lol

This is such a stoopid challenge. It would never have occurred to me to go big to get the decimal point. 😁

Dude your content is so good, how did youtube not recommend this before?

[claytonsingh]

Wonder if you could do the same thing by using minus and brackets? Would have to figure out how to do the decimal?

-2: --[--[-[]][-[]]][-[]]
-1: --[-[]][-[]]
0: -[]
1: -[--[-[]][-[]]]
2: -[--[--[-[]][-[]]][-[]]][-[]]
undefined: [][[]]
NaN: --[][[]]

This Also Returns 10:
[[]]["length"]+[0]

Nice. Are there complex numbers in javascript? Natively? Maybe some constants, like pi, e?
I think I saw something similar in some CTF video, maybe from LiveOverflow, but it was about constructing strings, not numbers.
I like your visualization tool.

Could you represent the whole latin alphabet using only these symbols? Maybe print a "Hello World"

There is a JavaScript-based programming style called JSFuck that only uses six different characters to write and execute JavaScript code.

1:03 +[] is basically a shorthand for
+[].toString()
The [].toString() returns "", and since an empty string is a falsy value, casting it to a number will return 0
That's why +[] === 0

"My key 1 is broken"... Oh, so that explains why he built this way to generate numbers for you...

Great way to obfuscate your code. Immagine someone reading that code! 🤣🤣

Next challenge every Letter in englisch alphabet

Can you call a function with only these three characters?
